[SOLVED] How I can detect when the modules window is open in the Delphi IDE?

I'm writing a Delphi plugin and I need detect when the Modules (View - Debug windows - Modules) window is open (attached to IDE Editor). I'm using the IOTAEditorNotifier to get notified when a new Editor window is open, but only works for source files.
This is the code used to receive the notifications from the IDE Editor.
uses
  Classes, SysUtils, ToolsAPI;

type
  TSourceEditorNotifier = class(TNotifierObject, IOTANotifier, IOTAEditorNotifier)
  private
    FEditor: IOTASourceEditor;
    FIndex: Integer;
    { IOTANotifier }
    procedure Destroyed;
    { IOTAEditorNotifier }
    procedure ViewActivated(const View: IOTAEditView);
    procedure ViewNotification(const View: IOTAEditView; Operation: TOperation);
  public
    constructor Create(AEditor: IOTASourceEditor);
    destructor Destroy; override;
  end;

  TIDENotifier = class(TNotifierObject, IOTANotifier, IOTAIDENotifier)
  private
    { IOTAIDENotifier }
    procedure FileNotification(NotifyCode: TOTAFileNotification; const FileName: string; var Cancel: Boolean);
    procedure BeforeCompile(const Project: IOTAProject; var Cancel: Boolean); overload;
    procedure AfterCompile(Succeeded: Boolean); overload;
  end;

procedure Register;
